UNITED STATES PATENT CHARLES E. STELLER, OF MILWAUKEE, WISCONSIN.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 358.579, dated March 1,1887.

Application filed November 10, 1886. Serial No. 219,009. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES E. STELLER, of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented new and usefulImprovements in Transon1-Lifts; and I do hereby declare the following tobe a full, clear, and exact description of said invention, referencebeing bad to the accompanying drawings, and to the letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 represents a front view, and Fig. 2 a side View, of atransom-lift embodying my improvements; and Figs 3 and 4 are details.

Like parts are represented by the same reference letters throughout theseveral views.

A represents that part of the transom-frame with which the transom-liftis connected. B represents that part of the casing to which thetransom-lift is attached.

By my improvement the guide-bearing O is made flat instead of round, andthe sliding bracket D is provided with an elongated aper ture, a, forthe reception of the guide-bearing O, to which it is nicely fitted. Anaperture is formed at 0 in the bracket D for the reception of the linkE. The bracket D being thus held in its proper position by the fiatguideplate, I am enabled to use the peculiar connecting-link E (shown ofcylindrical form and having loosely-fitting circular bends b and d)without liability of said bracket D turning or inclining, as saidbracket is not in any way dependent on the link E to prevent it fromturning, while with a round or cylindrical guide-bearing,0,a closely-fitting joint between the link E and the sliding bracket D isnecessary to retain said parts in their proper position.

To enable me to adjust the link E upon the transomarm F nearer to orfarther from the transom, as may be required to conform to moldings ofvarious widths, I have provided said arm F with a series ofretaining-notches,

g g, which are formed in the ridge or elevation h, whereby it is obviousthat the upper end of the link E may be moved toward or from the end ofsaid arm F and adjusted at any point in line with the lifting-rod G. Informing the eye 01 the end of the rod of which it is formed is so bentas to leave a small space, a, between the rod and the arm F for thereception of the ridge h. WVhen inserting the arm Fit is so turned as tobring the ridge h into the space a when it is moved to the desired notchg. It is then turned in the position shown and secured to thetransonrframe, in which position the notches g engage upon therespective sides of the linkand hold it in place.

The flat guide-bearing O is preferably secured to the casing upon twosupporting blocks or washers, H H, by ordinary screws, I I. The plate 0may, however, be elevated or sup ported upon shoulders or fasteningplates formed in one piece therewith and the separate blocks H Hdispensed with. i

The lower end of the lifting-rod G is supported in an open thimble orbracket, J, in which it has two bearings, b b, formed in the respectivesides of the bracket or thimble. Midway between the two bearings Z) I)is a handscrew, K, which, as it is screwed inward, impinges against thelifting-rod G, whereby the lifting-rod G is fastened at the desiredpoint of adjustment.

A twofold object is attained by the open bracket or thimble J notattained by a solid-rod support of the ordinary construction. First, bythe form shown I am enabled to rivet or upset the inner end of the adjlisting-screw K, so that it cannot be accidentally withdrawn; and,second, the frictional contact of the lifting-rod G is increased byhaving two bearings instead of one, whereby the same is rigidly held atthe required place of adjustment by the hand-screw without the aid ofnotches or depressions.

It is obvious that when the screw K is turned down firmly against thelifting-rod G,midway between the two bearings b b, the pressure of thescrew thus applied against said rod, at a point where there is no directresistance, has a tendency to slightly bend said lifting-rod rearwardbetween said bearings b b, and the rod is consequently held much morefirmly than it would be possible to hold it in a solid bracket of theordinary construction.

The several central or intermediate rod-supporting brackets, L, betweenthe guide-bar O and the adj usting-crew K, are so formed that they maybe cast in shape to be attached Without drilling holes for the screws.As the screwholes and the aperture for the lifting-rod are formed atright angles to each other, it becomes difficult to make such bracketsin the ordinary form without drilling either the screw-holes or the holefor the rod.

Notches h h are cast in the upper and lower ends of the fastening-plateM for the reception of the screws, whereby I am enabled to cast suchparts in shape to be used without any machine-work thereon.

I am aware of the state of the art as'shown in Patent No. 148,538, andmake no claim to the device therein shown; neither do I claim 'atwo-armed bracket for supporting the liftingrod of a transom-lift,broadly, nor a set-screw upset upon its inner end, as they havepreviously been used in various ways.

What I claim as new, and desire to secure by Letters Patent, is

1. In a-transom-lift, the combination of the transom-arm F,having ridgeor elevation h,provided with a series of link-retaining notches, g g,for the reception of the upper eye of the connectinglink E, andconnecting-link E,

communicating'between said arm and the lifting-rod, substantially asshown and described.

2. In a transom-lift, the transom-arm F,hav-

ing a ridge or elevation, h, provided with a series of link-retainingnotches, g g, with .a connecting-link, a bracket, and an elevatedguide-bearing,substantially as and for the purpose set forth.

3. In a transom-lift, the device-for locking the lifting-rod, consistingin the combination of the bracket J, having two rod-bearing apertures, bb, for thereception of the liftingrod G, lifting-rod G, and hand-screwK, arranged in a screw-threaded aperture at right angles to saidlifting-rod and adapted to impinge on said lifting-rod midway betweensaid bearings b b, in the manner and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES E. STELLER.
